Potent-cal Sepia. 23, midi. I-Sivied and. this appiicacion filed october To all 10 5.0772, may conceive .e ii; known that :5, Bios-moi: Ella-Now, ii siih iect of the Emperor of? @i-emiimy, iesiiling :it Siiii-cgmri Germany, have ini'cniecl c-erlain new and useful improve/merits in iiiniisiurcsfor Magneto-Induction Mo.- chines; and I do hereby cleclme the followllig to be a full, clear, and exact description of th: lHVCILtlOY}, such as will enable others skilled in the art to which it ap ierlains to make and use the same.

This invention relates lo the construction of ormalurcs O1 bobbins for magneto induction machines of the hype usually known as nmgneios. in ihe usual construction of such mac zines the arms-Hire 01f bobbin is mach;- up of a body portion carrying o wi'i glin which the cleoti-omoiive force 3n- ;cluced, and two hemi picces which twice in each revolution, bridge across the space be tween the mncinet poles and divert the lines of force, fi'oin thefiath through ihe body of 'l a bobbin and through the Winding carried hereby. It is customary to support those aob'oins for rotation in the ma ic field by means of two axle pins exiioi mei'ricaily from the body poi. hobhihs 21ml suitably jouinaled of thenmchine. With such coo liZipGSSlblQ to slip a, previously on the hody or coil-carrying poi: hoohii.

Zhis application is a division. of my copending application, No. 520,931, filed October 4, 1909, which iniiilficilifi cover generically the brood idea of my m motion, and specifically oiic particular form thereof in which the body portion is over hung by the head pieces. In ihzit specific form. a previously Wound coil cai'inoi; he slipped, on to the coil-carrying; portion, although the coil may he Wound on the body portion. withou? interference by the axle v t In the puriiculor modification constitii ll'lif the invention covered by the present of plimiioii, tlie'hezicl p. merge into the Emily ,poi'lion at one end Wl'illfllli; any overhang so thzitiho coil may be cntii-ely formed uncllhch slipped in 'pluco on the hocly pop lion.

[n l-hc accompanying drawings illusfi'ol. ing my invcniion, Figure 1 a View ot a. hohhin with the coil in place; Fig. 2 shows magneto with {in arn'iaturc similar iothat of 1; Fig. 3 shows a. modified form of obbin; anl Fig. 4 shows a magneto with an mic-tine similar to that of Fig. 3.

inv each of ihe drawings a ihc body or coil-carrying portion of the bobbin, 5 and 0 are the head pieces find a? and c are the axle pins In Figs. and 4%, 7' indicates the magnot frame of so ordinary magneto, and g the pole pieces of the magncrofi'zime, is well known.

In all the figures the head pieces are fiattcnecl so as to have substantially the same thickness as the body portion a. The bobbins shown have a body or coil-carrying poi-lion a iiIHl ihe hit-ad pieces Z) and c which carry i'he axle pins (Z and a at: one exliiemity and Til ihe other cxiremity merge into the body portion, that is Without any overhang", By this consiiuoi'ion, a, previously wouncl coil may he slipped on to the lJULly' portion to the. position shown. It is preferable to arch the coil-carrying part of the bobbin in order to more securely retain thoooil in place. The axis 01 the bcrly-portioii,a may he at right angles to the axis of the axle pins (1-, e,'

as shown in ,3, or these axes may be slightly diilei'eiit from this perpaniculm' arrangement, as showi in Fig. 1.

armature including axle inns may oo forged or pressed 01: otherwise formed of a single pieco oi metal, or the invention may be embodied in armature made up of assembled I stood.

if 'l-hc armature is to he DSQiilhiiEil", .Lll she is as will be readily underwell-lmowii by moons of a cam and bi cliioccly upon the ho'hhin iiseh at ii Fig. 1.

Having i I. claim is:

1. In a bobbin ior magneto induction ma chines a ci'iil-ceiiyi'zig body portion, head pieces merging into the body poi-lion :it one and, and oxlo pins extending from tho heed pieces, Wh r-rchy a previously Wounolcoil ins-y he slipped on to the hoiiy poi'iion; subsizmtiolly is (l'zilllbfil. I

Ahoohin ior magneto induction mo chines hoviiig a coil-carrying hocly portion, howl pieces merging into the hocly ortion not one end, and axle pins extending from the head pieces, the body portion being COHVXECl do springs, then ilio com moy ho formed as llilfllfikliifid:

h'us described my imventiomwhot to receive and retain a previously Wound coil; substantially as described.

3. In a bobbin for magneto induction machines, acoil-carrying body portion, fiat head pieces extending. from the body por tion, and axle pins extending from the head pieces, the axis of the body portion being angularly disposed with respect to the axis of the axle pins; substantially as described' 4. In a bobbin for magneto induction Ina-3, chines, n coil-cqrrying body portion having liea'd p1eces,' and axle pins extending from the head pieces, the axis of the axle pins being substantially at right-anglesto the axis of the body portion; substantially as described.

5, In a, bobbin for mafineto inductioninnchines, a coil-carrying ody portion, head pieces merging into the body portion at one of the body portion being singularly disposed with respect to the axis of the axle pins; substantially as described.
